Predicted to enable oxidoreductase activity. Predicted to be involved in response to oxidative stress. Predicted to act upstream of or within several processes, including adult walking behavior; negative regulation of neuron death; and negative regulation of peptidyl-cysteine S-nitrosylation. Located in nucleolus. Human ortholog(s) of this gene implicated in cerebellar hyplasia/atrophy, epilepsy, and global developmental delay. Orthologous to human OXR1 (oxidation resistance 1).
